Hướng dẫn sử dụng và sách hướng dẫn người dùng tai nghe Bluetooth

The Bluetooth Headset category encompasses a wide variety of wireless audio devices commonly sold under generic or white-label brands found on major e-commerce marketplaces. These products provide hands-free communication and audio streaming solutions for drivers, office workers, and mobile users.

This section archives user manuals and reference guides for models such as the BH-M97, which share common operational standards like Bluetooth V5.0 connectivity, noise-cancelling microphones, and multi-function button controls. Common topics found in these manuals include pairing instructions for Android and iOS, resetting factory connections, and understanding LED status indicators.

• How do I put my Bluetooth Headset into pairing mode?

  For many generic models like the BH-M97, ensure the headset is off, then press and hold the Multi-Function Button (MFB) for 5-8 seconds until the LED flashes Red and Blue alternately.

• What is the pairing password?

  If your phone requests a PIN or password during connection, try default codes such as 0000, 1234, 1111, or 8888.

• How do I reset or delete paired records?

  With the headset powered on, typically you press and hold both the Volume+ and Volume- buttons simultaneously for 5 seconds until the LED flashes rapidly.

• Can I connect to two phones simultaneously?

  Yes, many models support multi-point connection. Usually, you pair with the first phone, turn off Bluetooth on that phone, pair with the second phone, and then re-enable Bluetooth on the first to connect both.
